PCV membrane

[Goatz]

Hi all,
I noticed that the vacuum pressure in my engine is particularly strong to the point that I cannot unscrew the oil cap without pliers.
I am thinking that the PCV membrane could need replacing as I am over the 100k mark now, but I cannot find any guidance for how to get into the PCV.

Any idea how I can open the PCV cover on the rocker cover?

Thanks

ah ok, it seems that the pcv valve is built into the rocker cover and can only be replaced by replacing the whole rocker cover (!). Another great design!

You are correct. The PCV is built into the rocker valve cover. I am going to do a DIY replacement video of the rocker valve cover on the 156THP MK1 sometime next week.
